3D-LF-Analyser with Data Logger NFA1000
established as “Gold Standard” for EMF professionals
The NFA1000 is the top of the NFA line, the ultimate tool for dedicated building biologists. With a fraction of the usual amount of time required, all LF sleeping area measurements can be performed compliant with the SBM regulations, and it also opens up completely new insights for the mitigation of "dirty power". The intuitive NFAsoft evaluation software is included.
Frequency range: 5 Hz to 1000 KHz (compensated)
Also includes modern power adapter radiation
reducible to 400 KHz for TCO measurements

Product information "3D-LF-Analyser with Data Logger NFA1000"
The NFA1000 supports EMF professionals with dedicated innovative features
- THREE-dimensional potential-free measurement of the electric field - without the necessity of an external cubicle sensor (thanks to our patents DE102008045360 and DE102007025911).
- The potential free measurement of a sleeping area at 9 individual spots is optimally supported by the firmware of the NFA1000 allowing it to be fully completed in less than a minute. With a mouseclick, NFAsoft supplies the frequency and axis specific visualisation of the measurement.
- A compact 3D magnetic field sensor is integrated – as in all NFAs.
- Electric field measurement versus ground potential is possible with an integrated sensor or with the optionally available TCO conformed probe TCO3.
- The integrated voice recorder makes a meaningful measurement even more efficient.
Furthermore all common unique features of the NFA series are implemented:
- Parallel to the true 3D value of the magnetic field in the entire frequency range, the three axes of the field, railway and mains current as well as natural and artificial harmonics ("dirty power") are recorded separately.
- Powerful PC evaluation software NFAsoft included. Extensive graphics and statistics functions (eg 95th percentile, etc.).
- Continuous measurement guaranteed - even intermediate maxima are stored 10 times per second on the supplied SD card.
- Input socket for simultaneous RF recording with external RF analyzer or deeper analysis using current clamp / current loop.
- Compact integrated sensor for the magnetic field allows precise measurement even in very inhomogeneous fields.
- Li-ion batteries for 36 hours of uninterrupted recordings at ten full data sets per second.
- The product information leaflet on the three NFAs is available for download below. It comprises an overview over the features which allows for an easy comparison.
- Also please find the most current version of the firmware and NFAsoft in the downloas section of our homepage.
- For a better understanding of the extensive measurement and analysis possibilities of the NFA meters, please also read the manual carefully, as it is part of the meter specification (available for download below).
